[Galaxy Note II General] jujuburi:
★★★This topic is for them who are having problems with stock charger and cable. If you don't have any problems, ignore this ★★★

Well, since I purchased my Note 2, I kept facing this slow charging problem. Now what is slow charging some of you will ask? Well, it's simple. The device is taking more than normal time for charging. Now how do you know the default/should be rate for charging? Simple again. The AC adapter clearly says output rate as 2000 mA or 2.0 A. So with that calculation Note 2's monstrous 3100 mAh should be fully charged with 2 hours. But as we've seen steady 2.0A is not the output case in some/many scenario, so add another 30 mins to it. So whatever it is, from 0-100%, the device shouldn't take more than 2 hours 30 minutes.

And for me, it was taking around 5 hours! Sometimes 4 hours 30 minutes, and if it's very fast then 4 hours. Well I was never gonna wait 4 damn hours before going to my office and irritate myself, and I don't have the habit of charging overnight, unless I absolutely need it.

So I kept calling my retailer, asked for replacement, and they did, well, you won't believe, they replaced three times actually, so I had three different Note 2, with three different charger. Well, each of them acted absolutely fine at first 3-4 charge, then the problem was back again and again. I in fact turned off the device and put it into trash once.

Then I thought let's try some different USB cables, I tried my friend's Galaxy Ace cable. Charging current kept fluctuating between 1000-1200 mA. Which was better than those faulty stock cables, which provided steady 900 mA. Sometimes it even was detecting the AC current as USB, which would provide a mere 460 mA and would take God knows how long! Then I found my piece. I went to my retailer, frustrated and angry, asked them to give me the thickest and shortest possible cable, and they provide me one from a Samsung phone's box, but I can't recall which device was that! And then I sat there for half an hour, kept plugging and unplugging, and the current rate was rock steady at 1800 mA. I took it, paid just 10$ and came back.

Since then I have charged my phone almost 10 times and the current rate never went below 1800 mA / 1.8 A.

This is the cable I am using, do notice that it has 5 pin set up against stock cable's 4 pi, if that matters in any way, and it's about 10% thicker than the stock cable and also about 9" shorter.

And how will you monitor the charging current, three ways are there,

1- Battery Monitor (yet I don't know how to exactly use it)

2- If you are rooted (which is a must anyway), then just go to, /sys/class/power_supply/battery/current_avg

3- Use the app from the link below. It basically reads the current value just exactly as above but it saves the time to go into that file every time. A big thanks to Deadvirus.

Thanks to this post and it's poster for informing us about the current output reading path,
